The Viceroy (Limenitis archippus) is a North American butterfly with a range from the Northwest Territories along the eastern edges of the Cascade Range and Sierra Nevada mountains, southwards into central Mexico.
The Viceroy is well-known for its mimetic resemblance to the Monarch (Danaus plexippus). The black median line across the hindwing is the quickest way to distinguish it from the Monarch. These two species can even be separated on the wing by their distinctive flight: Monarchs have a leisurely, floating flight and hold their wings at an angle above the body when gliding, while Viceroys hold their wings in a flat plane when gliding, a behaviour characteristic of the genus Limenitis.
Great Slave Lake, NWT east to Nova Scotia, south to Florida and Mexico (Layberry et al. 1998, Scott 1986). Extirpated from southern BC (Guppy & Shepard 2001).
Usually found in open, moist areas where willows grow.
Non-Migrant: No. All populations of this species make significant seasonal migrations.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.

Adults eat flower nectar, aphid honeydew, moisture from rotting wood, fungi, dung, mud, sap and other sources. Males both perch and patrol for females (Scott, 1986).
Not of concern. Extirpated in BC (Guppy & Shepard 2001).
Degree of Threat: D : Unthreatened throughout its range, communities may be threatened in minor portions of the range or degree of variation falls within natural variation
Comments: A widespread species with some geographical and much individual variation. Two subspecies are almost universally recognized: FLORIDENSIS (mainly Florida) and OBSOLETA (southwestern USA and adjacent Mexico). Subspecies LAHONTANI (Nevada) is more or less transitional to OBSOLETA. Subspecies IDAHO needs to be reevaluated. It is close to typical ARCHIPPUS but probably shows some tendancy towards LAHONTANI. Based on the illustrations in its description and examination of additional published illustrations and specimens of eastern viceroys, dorsally IDAHO seems to fall mostly within the range of variation of northern transcontinental viceroys but the ventral tan areas are paler than at least eastern populations (D. Schweitzer).
